LAS VEGAS — Richtech Robotics has secured an order for 200 autonomous cleaning robots from an unnamed national retailer, giving the service-robot developer a defined five-year rollout with a large retail customer.

A filing  with the Securities and Exchange Commission on Sept. 21 reported the deal signed on Sept. 18. The customer agreed to purchase and deploy 200 DUST-E robots over five years. The agreement also covers automated reporting, remote support and other services.

Richtech did not disclose the order value, deployment timeline, number of stores, or the retailer's identity. The Las Vegas-based company did not respond immediately to a Robot24.com inquiry seeking additional details and confirmation of the customer.

The order follows a master services agreement Richtech signed with the same customer in August 2025. In the original SEC filing, Richtech described the customer as “one of the largest retailers in the world.” The two-year agreement established a framework for individual projects but did not specify robot volumes at the time.

Richtech began operating sixteen robots in a retail setting in November 2025. The two‑year agreement established a project framework without specifying the number of robots. The company’s latest filing does not say whether those robots were DUST-E models or whether they are included in the new 200-unit commitment.

The unidentified customer could be Walmart, but there is no evidence to back this up. Richtech has an existing relationship involving Walmart stores: in 2024, the company announced plans its cleaning, beverage and service robots at a One Kitchen restaurant inside a Walmart in Rockford, Illinois.
The robots were installed through Richtech's restaurant-management business. That deal was separate from the retail master services agreement, so it does not make Walmart a customer under that retail contract.

The agreement does not imply immediate deployment of 200 DUST-E robots, which Richtech markets as an autonomous commercial floor-cleaning system for retail stores and other facilities. The SEC filing states the customer will purchase and install the machines over five years; no annual delivery targets or pricing were specified.
